Tiles are spaced between

Not sure if I am the only one experiencing this but when I load Bing or OSM tiles, the 4 tiles have space between them. It seems like a cross between the 4 tiles in drawn into ArcMap. I am using ArcGIS 10, with SP3 and all previous hotfixes. I have resintalled
ArcGIS and it went away for a day but it returned just now. Not sure what's going on. I thought you might be able to help me. Thanks.

Also, it seems that the size of tiles for Bing and OSM has changed from 256 to 230 pixels. I thinks this causes the spaces between tiles. Just guessing though.
